No feedback on itemised billing request

I went into a vodacom store at The Glen and enquired about itemised billing I was told that they are not able to assist and I need to contact vodacom on 082111. I phoned the help desk and was told to fax a request to vodacom the consultant also said that she will log a request. I was put on hold for 15 min and dropped the call I did however fax the required info to vodacom requesting that a bill showing the numbers I contacted from Sept to date is provided I provided the reason why I need itemised billing my ID my cell number a copy of my ID and how the can deduct the fee this was two weeks ago to date I have not received any feedback. This poor customer service and I am disappointed with the service I urgently need the itemised billing and have no idea what to do in order for someone to respond and assist with my request
